Bu, Montréal, Québec

Concierge.com's insider take:

A minimalist wine bar in the happening Mile End neighborhood, Bu benefits from having a young and easygoing staff with a no-snobbery approach to wine connoisseurship. As a result, Bu is an inviting stop for both newcomers and aficionados. Twenty-five vintages are available weekly by the glass, and the bottle list is 500 strong. A bonus for the thirtysomething crowd: It's open late and also serves small Italian dishes, such as vitello tonnato or Caprese salad.
